From 3f3048547fe9f670288f7d177b410c1bfeb4504e Mon Sep 17 00:00:00 2001 From: Paul Date: Fri, 26 Jun 2026 17:54:46 +0000 Subject: [PATCH 01/11] Implement agent-rules package: library + CLI Core library (pure ESM, Node >=22): - rule discovery/parsing (.md/.mdc front-matter, inline + YAML-list globs) - recursive glob matcher with full multi-** support - diff utilities (getDiff incl. untracked, scoping, line map) - prompt builder, Zod-validated finding parser - filtering pipeline (dedup, diff-line, priority + test discount) - runReview orchestrator with bounded concurrency and per-rule failure isolation CLI (agent-rules): exec-only transport delegating to a local agent (claude/codex), resolution order --exec -> launching agent -> PATH -> fail, text/JSON output, exit codes 0/1/2. 36 unit tests; typecheck and build green.

18:01:34 +0000 Subject: [PATCH 02/11] Verify live transports; add smoke + verify scripts Verification against real agent CLIs surfaced two fixes: - claude profile: parse the --output-format json envelope and surface is_error/result (e.g. "Not logged in") instead of an opaque non-zero exit - codex profile: add --skip-git-repo-check so `codex exec` runs headlessly outside a trusted dir Confirmed end-to-end: codex produced a correctly-structured blocking finding. Adds: - scripts/smoke.sh: hermetic end-to-end CLI test via a fake transport (CI-safe) - scripts/verify-transport.sh: live check against a real claude/codex (manual) - yarn smoke / yarn verify:transport scripts - README transport notes + development section Co-Authored-By: Claude Opus 4.8 --- README.md | 25 +++++++++++- package.json | 4 +- scripts/smoke.sh | 79 +++++++++++++++++++++++++++++++++++++ scripts/verify-transport.sh | 44 +++++++++++++++++++++ src/exec-adapter.ts | 66 +++++++++++++++++++++++-------- 5 files changed, 200 insertions(+), 18 deletions(-) create mode 100755 scripts/smoke.sh create mode 100755 scripts/verify-transport.sh diff --git a/README.md b/README.md index 6048042..1f168cb 100644 --- a/README.md +++ b/README.md @@ -14,7 +14,7 @@ you decide how to surface them). ## Install ```sh -npm install agent-rules +yarn add agent-rules ``` Requires Node ≥22.

Rules are authored as plain Markdown files with YAML front-matter and evaluated by an LLM against the changed files in a diff. + +The package is LLM-agnostic and platform-agnostic: callers supply their own LLM adapter and decide how to surface findings. The package owns rule parsing, glob matching, diff scoping, prompt assembly, output validation, and core post-processing filters. + +--- + +## Goals + +- Rules must be human-readable and editable without tooling. +- Rule applicability is determined by file glob patterns, not by hardcoded lists in application code. +- Each rule is reviewed independently so that a single slow or failing rule does not block others. +- Findings must be anchored to specific lines in the diff, not the full file. +- The package must not hardcode an LLM provider, git host, or code review platform. +- All thresholds and limits must be configurable by the caller; no behaviour-affecting constants may be hardcoded. +- The package must be publishable to npm as a single, pure-ESM package targeting Node ≥22. +- The package must ship a CLI that can be invoked via `npx` / `yarn dlx` without writing any Node.js code. + +--- + +## Package overview + +### Installation + +```sh +npm install agent-rules +# or +yarn add agent-rules +``` + +### Public exports + +```typescript +// Types +export type { AgentRule, Finding, ReviewResult, RunOptions, LLMAdapter }; + +// Rule file utilities +export { collectRuleFiles, parseRuleFile }; + +// Glob matching +export { matchGlob, matchGlobs }; + +// Diff utilities +export { extractChangedFiles, extractDiffSections, buildDiffLineMap }; + +// Core filtering +export { deduplicateFindings, filterFindingsToDiff, prioritizeFindings }; + +// High-level runner +export { runReview }; + +// Diff acquisition (used internally by the CLI; exported for programmatic use) +export { getDiff } from './diff.js'; +export type { DiffSource } from './diff.js'; +``` + +All exports are named.
